Ceramic mounting wafer is the key to raising LED performance and lowering cost
The use of light-emitting diodes (LEDs) has continued to grow in recent years due to their low power consumption compared to incandescent bulbs and fluorescent lights. Kyocera has succeeded in developing a ceramic mounting wafer for LEDs, which has contributed greatly to increasing LED performance and lowering costs.

First, fine ceramic material is used for the wafer. Compared with conventional materials, ceramics have good insulation, heat dissipation and reflectance. Second, costs are reduced by producing high-precision large-scale wafers. Many individual wafers can then be cut from the large wafer. Next, compared with previous processes, Kyocera uses new laser-processing and machine-processing technology capable of cutting with fine precision. These processes also raise LED performance.

At present, Kyocera's ceramic mounting wafers are used mainly for LED lighting. We will continue to explore other applications, pushing fine ceramic technology to broaden the possibilities of LEDs.
